IMPROVEMENT IN CORN-SHELLERS.

Specification forming part of Letters Patent No. 122,740, dated January 16, 1872.

To whom it may concern:

Be it known that I, HUGH SELLs, of Vienna, in the county of Elgin, in the Province of Ontario and Dominion of Canada, have invented a new and useful Improvement in Corn-Shellers 5 and I do declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and making part hereof, in which- Figure l is a perspective view of my improved corn-sheller; and Fig. 2 is a cross-section on the line so :v in Fig. l.

Similar letters of reference indicate corresponding parts in the several figures.

The nature of this invention relates to anV improved and simplified machine for shelling corn; and it consists in the peculiar arrangem ent of a corrugated segment or concave plate with relation to a toothed drum rotating in an iron box or frame in such a manner that said concave will press the corn-ears against the drum, yielding to their inequalities of size, and in the construction, arrangement, and operation of its various parts, as more fully hereinafter set forth.

In the drawing, A represents a suitable frame, to which are secured the end plates of a cast-metal case, B, in the side plates of which the serrated cylinder C is journaled, whose shaft C is provided With a suitable fly-Wheel and crank, as shown. D is a segment, serrated on its concave face, and provided at each end with two projecting lugs, a., which are inserted in the slots b of the side plates before the latter are bolted to place. 'Betweenthe slots a vertically-slotted lug, c, is cast on the side plates, whose slot receives a single leaf spring, E, so disposed as to engage with the rear faces of the projecting lugs a of the consible, be laid in longitudinally parallel with the .i

axis of the cylinder, so that in the rotation of the latter the ear will be rolled down while held up to the cylinder by the segment, through the springs, with sufcient pressure to insure the stripping of the grains from the cob. It will be noticed that the springs are so disposed that the segment may give way to the larger ears fed :into the machine and avoid crushing them. In all cases theshelling action is continuous over the entire serrated surface ofthe segment, except where unusually large ears are to be shelled, for which provision is made by forcing back the upper part of the segment by means of an eccentric, F, pivoted to each side plate so as to bear upon and press back the upper studs c, and thus enlarge the throat of 'the sheller to receive them.

What I claim as my invention, and desire t0 secure by Letters Patent, is-

1. The combination of the lever eccentrics F with the studs c of the segment D, as and for the purpose set forth.

2. The combination of the segment D, provided with the lugs a, the slot b, and lugs c of the side plates, the eccentric lever F and the spring E, all constructed, arranged, and operating substantially as described and shown.

HUGH `SELLS.
